Goof: Bianca Castafiore refers to Captain Haddock as: Captain Hammock (twice), Captain Bangkok and Captain Hatbox.
Bianca Castafiore: (Watching herself on tv) That's not me, is it? How ghastly!
Thompson: lt's obvious that the gypsies who are camping on the grounds are guilty.
Thomson: We've searched their caravans, and not only did we find a pair of stolen scissors...
Thompson: ...but also a trained monkey.
Thomson: Now this robbery could have only been committed by a small agile creature capable of climbing the wall of the house.
Thompson: We're brought the monkey for some questioning...
Thomson: ...but he's not talking.
Tintin: l can't believe those gypsies are guilty. But if they didn't steal the emerald who did?
Tintin: (Lays on the grass and enjoys the piano music coming from the house, when he sees Mr. Wagner pass by on his bicycle) Well, well, Mr. Wagner must have the day off! That's funny. Who's playing the piano?
Tintin: Why Captain, you're up!
Captain Haddock: Yes, the doctor just left. He took off the cast! (He leans on the wheelchair that rolls away making Prof. Calculus fall down the stairs.)
Captain Haddock: l have bad news for you.
Bianca Castafiore: You have bad news?
Captain Haddock: Yes, l must leave tomorrow. They're clamouring for me at La Scala in Milan to do a Rossini opera.
Captain Haddock: (Grins widely) l'm terribly upset. (Giggles) Shattered! Are you sure you can't stay?
Bianca Castafiore: l know you'd like me to stay, Captain, but alas, l've made my reservations.
Captain Haddock: Yipee! Oh, happy day! (Dances)
Bianca Castafiore: What was that, Captain?
Captain Haddock: Oh happy day! My wheelchair's gone away!
Tintin: That opera 'La Gazza Ladra', I've got it!
Captain Haddock: What do you mean?
(Tintin climbs up a tree and checks the contents of a nest)
Captain Haddock: Be careful! Steady there!
Tintin: Aha! Two bits of glass, a marble...and... the emerald. l've got it!
Captain Haddock: What made you guess the magpie had it?
Tintin: The name of the opera: 'La gazza ladra'.
Captain Haddock: What about it?
Tintin: 'La gazza ladra'. lt means 'The Thieving Magpie'. Magpies will pick up anything that sparkles or shines, like a pair of gold scissors or an emerald. l knew there was a magpie around here.
Captain Haddock: You've cleared the gypsies of wrong doing. Some apologizing to do, gentlemen?
Thompson: Just our luck! The one time we manage to catch the culprits they turn out to be innocent.
Thomson: How true! You'd think they'd done it on purpose.
